Abstract
The invention relates to a method for treating surfaces of hollow parts, this method being a conversion treatment such as an anodizing, and to a method according to which the hollow pieces are completely immersed inside at least one treatment tank containing a liquid, characterized in that each hollow piece is immersed while making it execute at least one rotational movement so that air bubbles likely to be created inside the tank are removed from the inner wall of the hollow part.
